Capybara::ElementNotFound

I have problem with the capybara in testing the todo list with specific id.

here is my code edit_spec.rb

require "spec_helper"

describe "Editing to do lists" do

    it "updates todo lists successfully with corect information" do
        todo_list = TodoList.create(title: "my title", desc: "my desc")

        visit "/todo_lists"
        within "#todo_list_#{todo_list.id}" do
            click_link "Edit"
        end

        fill_in "Title", with: "new title"
        fill_in "Desc", with: "new desc"
        click_button "Update Todo List"

        todo_list.reload

        expect(page).to have_content("successfully updated")
        expect(todo_list.title).to eq("new title")
        expect(todo_list.desc).to eq("new desc")


    end

end

index.html.erb

<p id="notice"><%= notice %></p>

<h1>Listing Todo Lists</h1>

<table>
  <thead>
    <tr>
      <th>Title</th>
      <th>Desc</th>
      <th colspan="3"></th>
    </tr>
  </thead>

  <tbody>
    <% @todo_lists.each do |todo_list| %>
      <tr id="<%= dom_id(todo_list) %>">
        <td><%= todo_list.title %></td>
        <td><%= todo_list.desc %></td>
        <td><%= link_to 'Show', todo_list %></td>
        <td><%= link_to 'Edit', edit_todo_list_path(todo_list) %></td>
        <td><%= link_to 'Destroy', todo_list, method: :delete, data: { confirm: 'Are you sure?' } %></td>
      </tr>
    <% end %>
  </tbody>
</table>

<br>

<%= link_to 'New Todo list', new_todo_list_path %>

Failures:

1) Editing to do lists updates todo lists successfully with corect information
 Failure/Error: within "#todo_list_#{todo_list.id}" do
 Capybara::ElementNotFound:
   Unable to find css "#todo_list_"
 # ./spec/features/todo_lists/edit_spec.rb:9:in `block (2 levels) in <top (required)>'

i have checked some of the previous answers for this issue and i couldn't solve it.
